Patented June 17, 1930 UNITED STATES LEWIS C. BAYLES, OF EASTON, PENNSYLVANIA, ASSIG-NOR T INGERSOLL-BAND COM- PANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEW JERSEY Y OILIN'G DEVICE Application. filed September 3, 1927. Serial No. 217,428.

This invention-relates to oiling devices, but more particularly to an oiling device designed to be placed in a pressurefluid line carrying pressure to a fluid actuated engine I or motor.

One'object of this invention is to provide an oiling device simple and cheap to manufacture and which will'at all times supply oil to the motor regardless of the :position in which the oiler. is placed.

Other objects will bein part obvious and in part pointed out hereinafter.

In the drawings,

Figure l is a longitudinal sectional view of the oiler," and v Figure 2 is a transverse sectional view taken on the line 2-2 of Figure 1 and looking in the direction indicated by the arrows.

. Referring more particularly to the drawings, A is a casing internally threaded at B to receive the corresponding threads C of a fluid pressure pipe D. At the opposite .end of the casing A is a larger threaded opening E into which is screwed a plug. F having an internally threaded aperture G adapted to receive the threaded end Hof a fluid pressure pipe J Through the plug F a passage K is formed which has an enlarged portion L at its end. This enlarged portionis adapted to receive atube 0 which extends longitudinally through the'casing A and into an aperture P at the end of the casing. V l

The end of the plug-F which enters the 5 casing A has a reduced portion Q cylindrical in form and a further reduced and threaded portion R. Bythis stepped reduction of the plug end faces Q and R are formed. A heavy ring S havingan internaldiameter H 40 somewhat larger than the reduced portion Q of the plug F surrounds this reduced portion. An annulargroove .or channel T is cut in the inner face of thering S. A second ring or washer U having a central aperture'V fits over the threaded portion R of the plug F and cooperates with the end face Q, to form a guidewayfor the ring S. The ring U is. held in place against the face R by a nut W screwed onto the threaded portion R. Radial grooves X are cut in the face ofthe ring U and this face is brought in contactwith the assembling theoiler.

A hole Y drilled in the plug F has areduced portion Z and a tube 6 having a head 0 and a stem, or reduced portion (Z fits the hole Y tightly enough to prevent accidental ring S in turning of the tube 1) relative to the hole Y. A 'hole 6 is drilled longitudinally through the tube band meets a second hole 7 at substantially right angles near the lower end of the tube. Approximately midway between the ends of the tube 1), a second hole 9' is drilled at right angles to the hole 6. This hole 9 communicates with apassage -72. in the plug F and a tube j extends from passage /1- to the right hand end of the casing A.

An inclined hole k is formed in the plug F and has a threaded portion 0, a reduced portion 79 and a further reduced portion q.

From the cylindrical portion Q of the plug F a passage 7 extends communicating with the hole anda nozzle it extends fromthe hole .76 into the tube 0. A passage 8 forms a communication between the hole Y and a ring groove 2?.

In nearly all operations where compressed air'tools are used, the tools and the accompanying apparatus, such as air hose and oilers are necessarily subjected to some rough usage. Under these conditions it is impossible to keep an oiler in a fixed position in which it may have been designed to operate most efficiently. To overcome this difficulty andobjection to the type of oiler which is connected in a'hose line the pipe J through a passage O in the oiler and out to the-tool throughhose or pipe D.

The object of the oiler being placed in the line is to get a suitable quantity of lubricant into the passing stream of pressure fluid and thus into the tool being driven by the pressure fluid.

There is enough clearance between the face Q and the ring U to permit the ring S to take the lowest possible rposition regardless of the position of the casing A. Thelubricant will also seek the lowest part of the casing and pressure fluid is admitted to the reservoir through-the "passages 6, Y, s and t. It is I obvious that I as the *ring U "always falls to the lowest position, a portion of the ring groove 6 will always be uncovered "to admit pressure fluid -to the reservoir -A. The pressure fluid thus admitted forces lubricant into the i lowermost radial grooves This lubricant enters the "chamber formed between the cylindrical surface of the -reduoed :portion Q of plug F and the innermost face-of the ring S. It "will be noted that the passage 7" may 1 nottake the position :shown in the drawing'but is :just as apt "to "be found vertically over thezaplace in which it is shown. In such a contingency the annular channel T will carry the lubricantup to'the passage 7'. After-the "lubricant passes "through the passage r it is forced out'of the nozzle a and into the stream of pressure sage? may be'covered-or uncovered bythe cylindrical end 3 of the needle valve, thus regulating the quantity of "oil admitted to the passage 0.
